My present invention pertains to tool sup-- ports for machines employing rigidly secured tools and. relates more particularly to a tool post or' tool head construction wherein longitudinal and lateral adjustment of the tool is provi-ded. for, aswell as means for rigidly securing the tool in its adjusted position, and comprehends means for longitudinal adjust-ment independently of the lateral adjustment and vice versa, and the combination of a tool head having the above-named properties with a novel. form of tool hereinafter described. p

Some of the objects of my inventionare to provide a tool post or tool head of simple and effective construct-ion providing novel means for the longitudinal adjustment yof the tool and-for the lateral adjustmentof the tool without disturbing said longitudinal adjustment and vice versa, together with positive means for securing thertool` in its adjusted position.

I have illustrated niyminvention embodied in one ,torni of tool`heatl in the accompany-` ing drawings, in which like reference parts throughout .the sev-` acters indicate like eral views.

Figure 1 is a perspective of the upper portion of a tool head embodying my present invention; Fig. 2 is a vertical cross-section througli the center of the tool; Fig; 3 is a bottom view in perspective of the tool clamp showing the adjusting screw rrmoved, and Figs. 4 and 5 are a side elevation and a plan of the tool respectively.

llet'erri ug to the drawings the base portion 2 of the tool head is provided with a dove tail tonon 3 upon its upper surface and running across said upper surface. A tool car Tying portion #l or' the tool head is provided with a (love tail mortise in its under surface and is adapted to be Islidahly mounted upon the hase portion 2, the dove tail tenon 3 lengaging the dove tail mortise in the under surface of the tool carrying portion 4. The tool carrying portion ll is slit lengthwise of theV dove tai-l 4mol-tisse therein at 5, saidslit at 5 being of such a depth that when a screw 6, .which has' a shoulder 7 adapted to abut the tool. carrying portion 4 and threaded into theY is inserted loosely through one part of' said tool' carrying portion 4 and threaded' into the other art of said tool carrying portion 4e beyond) thesaid slit is tightened?, lthe two portions of the tool carryi-n rtion 4 upon he .slit will Eg either side of t brought together,- the spring' of the' metal@ permitting this. The `slit 5 is 'preferably made from the interior of thev dove tail mortise the tool carryingl portion adjacent one-inclined- `wallv of said mortise, and the screw 6 is in'- tise in the tool carrying portion 4 is ma.

chined it may be made very close to the same size as the tenon 3, or perhaps a trifle smaller, as the spring of the parts of the tool carrying portion 4 at either side of the slit at 5 will allow of saidl tool carrying por,- tion 4 beine forced u on the base portion 3 and the sliding of said tool carrying portion 4 upon said base portion 2.

The tool carrying portion his made flat upon its upper surface with a shoulder 8 along its rear side extending somewhat above the said upper surface. A channel 9 is provided transversely of the tool carry- Aing portion` 4 in the upper surface thereof der 12 upon "its under-surface adapted tov contact the upper surface of the ltool carrying portion'4. A screw 13 has a shoulder 14 which abuts the upper surface of the clamp 11. Said screw 13 passes loosely through the clamp 11 and is threaded into the tool carrying portion 4. The screw 13 passes `through the clamp 11 between the shoulder' l2 and the tool 10. It will be seen that il the screw 13 is tightened that end of the clamp 11 resting upon the tool 10 will '2d "When the l Qhy means of the. sci'ew 6.

secure the tool 10 'in its journal 9. The up# pei' surifaosoi" the tool 10 is poviiiod 'withA a -fsnmle thread somewhat in the foi-.m of a inox, and a screw 15 threaded `its entire isnfrth is oiaoed in a c lindrioal cajvit in the clamp 13.1. The cyiindrical cavity 16 runs gmmlleiiy oi' the tool 10 and is interacepts by the under surface of vthe damp l1 opening downward upon upper sull- 10 face 01"", the tool 10. The 15 is inl sorted from the side of the cmnp ll'iind its threads extending below the under sur* face of the lclamp engage the female threads or rack upon the Upper surface of the 'tool 1.5 10. The Screw shuts the inn-sr end of the cylindrical oafvity lf3 and it will he seen N that when tho soiow 13 is slighty loosened' a fine longituoiinal adjustment of the tool- 10' may be had by operating the screw lo; 'proper adjustment is made the screw 13 is tightened; The lateral adjustment of the tooi is accomplished. by sliding thotool carrying, portion 4r upon the oase .portion 2 and ssouringit by drawing in v'25Asifies of the ove tail mortise in tooi tgl-1i tenonl carrying portion 4 npon the dove if i f *us that many Changes if. rfoin ont of .the several parts this dei/ica' may .the spirit of my. invention.
